Nicki Minaj and Mariah Carey have been rumored to have already had several cat fights since "American Idol" started doing their auditions, but now TMZ has obtained a video of the two singers verbally assaulting each other.
During the "American Idol" auditions in Charlotte, North Carolina on Tuesday, Nicki caused filming to come to a standstill after swearing at Mariah Carey and threatening, "I'm gonna knock you out" ... sources tell TMZ.
In the video, Nick, wearing a white dress and her trademark pink wig, is fuming and is shouting at Mariah Carey as she waves her hands in the air."I told them I'm not f*ckin' putting up with her f**kin' highness over there."
Mariah, who is sitting two seats away from her with fellow judge Keith Urban in between the fuming ladies, replies "Oh why, WHYYYY .do I have a three year old sitting around me?"
"I can't see my kids, because you decided to act like a little crazy bitch and go all around the stage," she adds.
Sources say Nicki later threatened to "knock out" Mariah ... but she said it before the video starts.
According to MouthToEars.com, producers ended the auditions for the day so the two judges could cool down. We've confirmed that happened.
Urban and Randy Jackson try to keep the peace with Jackson even standing up and asking Nicki to "settle down, settle down."
Mariah has a $20 million contract with "American Idol", while Nicki is rumored to be getting between $8 million to $12 million for a year's contract. Click here to watch the video at TMZ.
